Application Notes: General

Food manufacturers must ensure that TiO2 is within safe levels and correctly listed on a product label. However, measuring TiO2 in food products presents some challenges for the analysis via common atomic spectroscopy. Titanium dioxide may also be present in foods as nanoparticles, which requires specialized measurement techniques if the nanoparticles are to be quantified separately. Agilent is developing the measurement methodology to help manufacturers meet these new regulations.

We explore some examples of physical and chemical concepts that can be demonstrated in STEM settings with easy-to-use and accessible equipment, such as the Omni-Cell.
